Jury, 1903.] THE ORCHID REVIEW. 207 
In the warm division of the Cool section there are a few Miltonia 
vexillaria yet in bloom, the majority being over, but a general treatmeat 
is still possible as far as watering is concerned, though with regard to 
spraying overhead only those that have flowered should be so treated. The 
Pleiones are now fast forming their bulbs, and should have every encour- 
agement to assist in the development of good, sound bulbs, by giving an 
abundance of water, which may be occasionally diluted with liquid cow 
manure, and the leaves kept clean and free from red spider. The tips of the 
leaves will soon begin to decay, but this is quite natural, and these should 
not be continually trimmed off with the mistaken idea of enhancing the 
appearance of the plants. 
Cypripediums of the cooler section, amongst which are included such 
as C. insigne, villosum, Boxallii, and the numerous hybrids derived from 
these parents, will need watering almost daily, as will also a large number 
ofthe warmer-growing kinds, always excepting the concolor section, Stonei, 
philippinense, Parishii, Lowii, Rothschildianum, Haynaldianum, and 
others of a similar nature. Selenipedium Schlimii is often a difficult sub- 
ject to manage; it should be potted in a compost of half peat and half 
loam, with a little moss, and stood in a moist position in an Intermediate 
house, always giving it plenty of water at the roots, but do not on any 
account allow any to ledge in the leaves. When grown well it is a most 
desirable Orchid, but otherwise it is a continual eyesore. 
In the Cattleya House there will now be plants in all stages of growth; C. 
Warneri, Gaskelliana, and Warscewiczii will be in the flowering stage, and 
the newly made bulbs will soon emit quantities of new roots; hence water 
in larger quantities will be required. C. Triane and labiata have their 
growths in a forward stage, and in many instances are showing sheaths 
They, too, should not suffer from want of water, but always allow the 
material to get on the dry side before another supply is given. C. Mossiz 
and Mendelii should only be watered in moderation, for though rooting 
freely, the moisture in the atmosphere will go a long way to satisfy the 
wants of these two species. The same remarks will apply to Lelia 
purpurata. This species should not be encouraged to make growth too 
soon, for it is those bulbs that are produced in the autumn that give the 
best results in the way of flower sheaths. C. Bowringiana is now growing 
strongly, and will need more water, and when new roots spring from the 
base of the pseudobulbs new material may be given if required. Re-potting 
is best done immediately the flowers have gone over. C. Skinneri requires 
large supplies of water when growing, as also does C. velutina, C. bicolor, 
and other thin-stemmed species. C. Dormaniana should now be growing 
freely in a position at the coolest end of this house, and new material may 
be given in small quantities when root action takes place.
